            <a name="what_is_7z_format"></a>7Z extension designates a
popular archiving format, created for
7-Zip, a
modern file archiver application written by Igor
Pavlov and released as freeware and Open Source software. 7-Zip
(often incorrectly shortened in 7zip) was originally developed for
Microsoft Windows platforms, and ported by p7zip (POSIX-7Zip) project
team on
Unix platforms.<br>
Spanned multi-volume 7z archives are designated by .001 extension,
incrementing file extension numerator for each successive volume of the
set - spanned 7z files are split byte-wise, this raw splitting
mechanism being compatible with Unix / Linux "split" command and
Windows utilities like HJSplit.<br>

compression ratio through powerful
compression
algorithms (LZMA, LZMA2, PPMd, BZip2, optionally optimized
Deflate), at
cost of more
memory and CPU
intensive compression process
- that however can take benefit
of
parallel computing on modern multicore CPUs.<br>
With Tino
Reichardt's codecs for Brotli, Lizard, LZ4, LZ5, and Zstd algorithms,
supported by PeaZip, 7z format features faster-than-zip compression /
extraction.<br>
On average test cases 7Z
format improves compression ratio 30-70% better over classic <a
 href="zip-file-format.html"><span style="font-weight: bold;">ZIP</span>
format</a>, and 6-7% better than <a href="what-is-rar-file.html"><span
 style="font-weight: bold;">RAR</span> file format</a> (WinRar's
native format, proprietary); 7Z compression compares favourably also
with new <span style="font-weight: bold;">WinZip's <a
 href="zipx-file-format.html">ZIPX</a></span><a
 href="zipx-file-format.html"> format</a>
in most cases.<br>
7Z format also features native UTF-8 support for filenames,
Rijndael / AES
encryption, and volume spanning.<br>

.7z is a good choice anytime

welcome the support for strong encyption to keep archived data private.<br>
It is recommended over zip format when enough time for compression or
backup is available, in order to provide better reduction of output
